Knowledge introduction to cloth wire

2014-11-18 09:02:00 Tips:

Insulated wire number of shares of each wire of the divided into single line and multiple lines, usually 6 square millimeter above the insulation of the wires are more strands of wire, insulated wire under 6 mm2 and can be a single line, also can be more strands of wire, we are called the single strand under 6 mm2 and hard line, multi-strand wire called the cord. Hard line with "B", said the soft line with the "R" said. such 

B series classification belongs to the wiring, so begin with such B 

V is PVC, PVC (plastic) 

L is the aluminum core code types 

R is the meaning of (soft), to do soft, is increasing the number of conductor types 

Wire and common insulating materials with polyvinyl chloride (PVC) and polyethylene, polyvinyl chloride (PVC) with "V", said the polyethylene with a "Y" said. such 

Insulated wire fixed together mutually insulated wire number, can be divided into single core and multicore, multiconductor can also be more than the single conductor is fixed in an insulating sheath. Within the same sheath can be more multiconductor to 24 core. Parallel multiconductor with "B", said the stranded type of multiconductor expressed in "S". such 

Understand the above content, you can easily see that the wire type of meaning, as follows: model name 

 

BV copper core PVC insulated wire; 

BVV copper core PVC insulated PVC sheathed wire; 

BVR copper core PVC insulated flexible wire; 

The RV copper core PVC insulated cord installation; 

RVB copper core PVC insulated flat cable cord; 

BVS type copper core PVC insulated ground cord; 

RVV copper core PVC insulated PVC sheathed flexible wire; 

BYR polyethylene insulated flexible wire; 

BYVR polyethylene insulated PVC sheathed flexible wire; 

RY polyethylene insulation cord; 

RYV polyethylene insulated PVC sheathed flexible wire
